Jean Poul Ramirez-Castillo appeals his guilty-plea conviction for conspiracy to im *784 port marijuana and conspiracy to possess with intent to distribute marijuana. He argues that the district court abused its discretion by denying his motion to suppress. Ramirez-Castillo’s voluntary and unconditional guilty plea waived all nonjurisdictional defects that occurred prior to the plea. See United States v. Lampazianie, 251 F.3d 519, 525 (5th Cir. 2001). Accordingly, the argument is waived and the conviction is AFFIRMED.
